LA'IHROP KAZAR, OF LEROY, ILLINOIS.

Specification forming part of Letters Patent No. 29,601, dated August14, 1860.

To all whom it may concern:

Be it known that I, LATHROP KAZAR, of Leroy, in the county of McLean andState of Illinois, have invented a new and useful Improvement inMole-Flows, of which the following is a full, clear, and exactdescription, reference being had to the accompanying drawings, in whichFigure 1 represents a plan or top view; Fig. 2, a plan of the underside; Fig. 3, aside, Fig. 4 a rear, and Fig. 5 a front, elevation of amachine embracing my improvement.

My improvement consists in a new and improved mode of constructing themole or drain plow, by means of which, while the upper part of theunderground or ditch is left in a solid and compact form, the sides andbottom will be left uncompressed, that the water may percolate freelythrough then1an object of the greatest practical importance, as withoutit such drains or ditches would be of no value.

To enable others skilled in the art to make, construct, and use myinvention, I will now proceed to describe it, omitting such parts of themachine as are not essential to a full understanding of my improvement.

In the accompanying drawings, the machine is represented as consistingof two landsides, A, connected together by a top or plane, B, set at anacute angle to the plane or path of motion of the machine, andprojecting over the sides to such an extentas topreventtheirbeingbrought in contact with the sides ofthe drain asformed,

to prevent compression of the soil. To the rear end of this top ishinged an apron, O, which rests on a. supporting wheel or pulley, D, ofwhich there are several in a set, so that by removing one andsubstituting another of greater or less diameter the apron may beadjusted to make a large or small drain, as required. The laudsides arealso made to project below the base of the plow, so as to form runners,as it were, on which theplow is to slide, to prevent compression of thebottom of the drain. Near the upper end of the plane B is passed orpierced an opening through the solid part of the plow, for the purposeof attaching the power by which the plow is to be propelled.

In the drawings, the inclined top or plane B is represented as being ofan equal width throughout; but it may, if desired, be made of a diamondor other suitable shape.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

The peculiar arrangement of the landsides A with respect to theadjustable apron O, as operated, and inclined plane D, the whole beingconstructed in the manner and for the purposes set forth.

In testimony whereofl hereunto set my hand to this specification.

LA'DHROP KAZAR.
